Read this article: https://en.tankiwiki.com/Promo_Codes
you said they dont expire. but when i entered them today, it says they expired. i am pretty sure i entered the correct codes. still it shows invalid. please help me.
The promo codes can be used only once. If someone already used the code, it will be expired.
